Description

Hands-free voice recording / playback device for vehicles {Apparatus for record / play of voice in hands free of vehicles}

The present invention relates to a hands-free, and more particularly, to a hands-free voice recording of a vehicle hands-free which can be prepared for a safety accident by connecting a device capable of recording and reproducing contents of a call or conversations in a vehicle to an earphone jack of a vehicle hands-free. / Playing device.

Recently, with the rapid increase in the number of wireless mobile phone users, various additional equipments for the convenience of wireless mobile phone users have been released. Among them, there are a number of devices related to hands-free for driving safety in automobiles.

The general configuration of the hands-free is connected to the cigar jack of the vehicle to be powered by using the interface located on the bottom of the wireless mobile phone, and is connected to the audio device of the vehicle to record and play back the voice.

Therefore, the conventional method of recording and playing back a voice has the inconvenience that the receiver must change the radio reception frequency when the radio is turned off or is being received in order to play the recorded voice.

A first object of the present invention is to provide a hands-free voice recording / playback apparatus for a vehicle that can be used by simply connecting a device for recording and playing back a voice to an earphone jack of a mobile phone in order to solve the problems of the prior art.

A second object of the present invention is to provide a hands-free voice recording / playback apparatus for a vehicle in which a voice is recorded at a location (memory address) that is easy for a user to recognize during voice recording / playback, and the address can be easily found. .

1 is a block diagram of a hands-free voice recording / playback apparatus for a vehicle according to the present invention;

Fig. 2 is a block diagram of a voice recording / apparatus for handsfree for a vehicle according to the present invention.

As a technical means for achieving the above object, the present invention provides a speaker amplifier for amplifying the earphone output of the mobile radio telephone to be audible in the vehicle, and amplifies the recorded voice during playback of the recording; A microphone amplifier for amplifying and transmitting a voice signal input through the microphone to a predetermined level; Voice recording / playback IC that converts the input voice signal into a digital signal, stores data in the internal memory according to a recording command, and converts and outputs the stored digital signal into voice. An input unit that performs a command for a find button to find; A microcomputer outputting a control signal for recording and reproducing according to a signal input from the input unit, and outputting data on a start point memory address of a track in which recorded or recorded contents are stored; And a track indicator displaying a corresponding number according to the data value of the memory address of the track output from the microcomputer.

The microphone amplifier is characterized in that the built-in automatic gain control circuit (AGC) for processing a constant volume according to the user's position.

The track control of the recording / reproducing apparatus has a feature configured to allow the user to directly designate a track starting point memory address of a content to be recorded and find and play the corresponding address after recording.

Hereinafter, with reference to the accompanying drawings will be described the present invention in more detail.

1 is a block diagram of a voice recording / playback apparatus for a handsfree vehicle according to the present invention, the configuration of which is amplified to be audible in the vehicle by amplifying the earphone output of the mobile wireless telephone (mobile phone) and recorded when playing the recorded contents. A speaker amplifier 17 for amplifying voice and outputting the speaker 18, a microphone amplifier 15 for amplifying and transmitting a voice signal input through the microphone 16 to a predetermined level, and a voice signal inputted as a digital signal. Audio recording / playback IC (13), which converts the data into internal memory according to the recording command and converts the stored digital signal into audio, and outputs it. An input unit 12 for performing a command for the control unit, and outputs a control signal for recording and reproducing according to a signal input from the input unit 12, and records or records A microcomputer 11 for outputting data on the memory address of the starting point of the track where contents to be stored are stored, and a track indicator 14 for displaying a corresponding number according to the data value of the memory address of the track output from the microcomputer 11. Is made of.

In this case, since the volume is not constant according to the position of the user, the microphone amplifier 15 includes an automatic gain controller (AGC: Auto Gain Controller) so that the voice is transmitted without changing the volume according to the position of the driver.

The track control of the recording / reproducing apparatus is configured to directly designate a track starting point memory address of a content to be recorded so that the user can find and play the corresponding address after recording.

Referring to Figure 2 the operation of the present invention configured as described above is as follows.

First, the driver connects the vehicle cradle 10 to the microphone / speaker jack (earphone jack) 20 of the mobile phone using a cable.

At this time, the mobile phone can be mounted on the mobile phone insertion unit 40 according to the user's intention.

In this state of connection, when the voice recording (call recording, recording in-car conversation) occurs, the driver or other user presses the record button 121 to record, and at this time, the contents to be recorded in the memory To assign a street address, look at the track indicator 14 and press the REW 123 or FF 124 button to assign it.

If "2" is displayed on the track indicator 14, since the current recording is stored in track 2, the driver may press track button 122 after finding track 2 when playing the current recording.

Accordingly, the driver or user can easily record and easily play back a voice in the vehicle.

On the other hand, the vehicle cradle 10 uses an EL (ElectroLuminance) element so that it can be seen at night.

The present invention is not limited to the above-described specific preferred embodiments, and various modifications can be made by those skilled in the art without departing from the gist of the present invention described in the claims. Of course, such a change is of course within the scope of the present invention.

As described above, according to the present invention, by simply connecting the audio recording / reproducing apparatus to the earphone (microphone / speaker) jack of the mobile phone via a cable, the recording / playback is performed simply, and the memory for each track to easily find the recorded contents By storing the voice in the voice, it is useful to the long-distance operator or the user who is busy.
